Steps if you are NOT able to launch Unfair Advantage:

Click the VIEWS icon in the Windows Explorer and choose DETAILS.
Navigate to the SIZE column and click it until you get the highest to the lowest file size.
Look for the PORTFILE.ADM file.
Choose a backup file (i.e portfile.r1 …, portfile.b1 …, portfile.d1 …, portfile.m1 …) which compares to the size of the PORTFILE.ADM file.

Delete the PORTFILE.ADM file and rename the backup file (i.e portfile.r1) to PORTFILE.ADM.
